In this activity, learners predict where a ball will go after it bounces off another object. Learners discover that the motion of objects is predictable based on laws of motion.

This activity (on pages 35-43) lets learners analyze a "herd of elk" to detect the spread of a bacterial disease called brucellosis.

In this math lesson, learners learn how to construct stem and leaf plots. Learners first estimate the number of drops of water that will fit on the head of a penny.

In this activity, learners investigate color vision as well as plan and conduct their own experiments.

This activity introduces the idea that computer scientists measure information by how "surprising" a message is.

In this activity, learners investigate various appliances and electronics, discovering how much energy each uses and how much carbon dioxide (CO2) is released to produce that energy.

In this activity, learners estimate risks associated with different events and compare their estimates to the real possibilities.

In this activity, learners use their understanding of probability to guess which color will be drawn from a bag.

In this sorting activity, learners play a game in which they try to identify the largest number of differences between two objects.

In this activity, learners determine the shape of an unseen object by bouncing a ball off the object.

In this activity, learners explore how the area of Arctic sea ice has changed over recent years. First, learners graph the area of Arctic sea ice over time from 1979 to 2007.

In this activity, learners develop their understanding of combinations as they create as many different kinds of tostadas as possible.

In this math activity, learners play a probability game and try to be the first to get to the end of the game board path .This activity guide contains a material list, black line masters for the game

In this math activity, learners play a game in which every roll can earn you counters, but if you roll the wrong number (6), you have to put everything back.

In this Cyberchase activity, learners use numbers to create CyberOlympic teams with the fastest times.

In this pencil and paper activity, learners work in pairs and simulate how astronomical spacecraft and computers create images of objects in space.

In this calculus activity, learners use a classic problem of geometrical probability to find an important mathematical constant (pi).

In this activity, learners help a poor cartographer color in the countries on a map, making sure each country is colored a different color than any of its neighbors.

In this math game (Page 14 of the Are You Game? PDF), learners determine the probability of getting an even versus an odd product using the numbers on a regular deck of cards.

In this activity related to climate change, learners create and explore topographical maps as a means of studying sea level rise.
